Cardiac pacemaker and pneumothorax. Coloured chest X-ray showing an implanted cardiac pacemaker (green, upper left) in a 77-year-old man. A pacemaker supplies electrical impulses along wires connected to the heart (wires visible here). These electrical impulses help to keep the heart beating regularly when a patient has an irregular heartbeat (cardiac arrhythmia). This anterior (frontal) view also shows the lung structure, with the left lung at right and the right lung at left. The lung seen at right is healthy, but the lung seen at left is compressed by a large pneumothorax (collapsed lung), with far less lung tissue visible on that side of the X-ray. A pneumothorax occurs due to trauma or lung rupture. It causes shortness of breath and pain on breathing. | |
